Synthetic Route of 261723-32-4 ,Some common heterocyclic compound, 261723-32-4, molecular formula is C7H6BrFO, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
To a solution of (3-bromo-2-fluoro-phenyl)methanol (2.750 g, 13.413 mmol) in dichloromethane (50 mL) was added manganese dioxide (9.32 g, 107.31 mmol) and the resulting mixture was stirred at 45C overnight. Once complete, the reaction was filtered through diatomaceous earth and washed with dichloromethane to obtain 3-bromo-2-fluoro-benzaldehyde as a white solid (2.24 g, 83%). lU NMR (400 MHz, DMSO-i ) delta 10.19 (dt, = 1.3, 0.7 Hz, 1H), 8.05 (tdd, = 6.8, 3.1, 1.5 Hz, 1H), 7.85 (ddt, = 7.9, 6.4, 1.5 Hz, 1H), 7.37 (tdt, = 7.8, 1.6, 0.8 Hz, 1H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 261723-32-4, (3-Bromo-2-fluorophenyl)methanol, other downstream synthetic routes, hurry up and to see.
